  I would like to do the following:
   * listen to music all over the room (so this probably disqualifies a
 5.1 setup?)
   * do semi-professional audio (voice recordings, singing, guitar, synth
 with MIDI keyboard)
   * watch a movie every now and then. That's not really important,
 though.
 Is that enough for you to hand me some advice on what to get? 
 You're not specifying the price range. However, I'm very happy with my
 KRK Rokit 6 active speakers, and I've heard that many others are happy
 with them too. They're about £450 in Norway.
 If you double that amount, you could go for the more expensive line of
 KRKs, you could take a look at the KRK V6. Other than that I've heard
 good things about DynAudio active speakers. If you really wanna blow
 your wallet you could consider the PMC Transmissionline speakers. They
 also come with or without built-in (pluggable) power amps, so you can
 deceide if they should be active or not.
 To me I prefer active speakers because:
   - They're more "heavy duty" than typical HiFi, and designed to
 withstand more harm than HiFi. At least it's supposed to be like that.
   - You get two seperate power amps. Don't tell me that one integrated
 stereo power amp is better. Highend HiFi amps often are built as two
 seperate amps, even with seperate trafos. This is a good design wich you
 get (much cheaper) with active speakers.
   - They usually have balanced inputs. Phono cables are crap. Period.
   - It's more practical in use with a computer than a HiFi is.
   - You can buy more speakers if you wish to make a 5.1, 6.1, 7.1 or
 even 10.2 setup.

First a good dealer that knows the business, is one you can trust and  has it
all.
  check out the Samson's, several nearfield speaker sizes and choices of {
silk / titanium / ribbon } tweeters. and engineered woofer. Ribbons seem to
be the cutting edge. Google "Jay Rose" a audio engineers engineer. A firewire
audio breakout box to handle the bandwidth. Proper cabling.
